1 and melamine resin are known, but the former is a one-dimensional (linear) polymer, and the latter is amorphous because it is bonded in a three-dimensional disorder. The S-triazine ring has 6π1 as a child thread, and the 6 atoms (3 carbons, 3 nitrogens) form the same plane, so if the π electron system can be expanded two-dimensionally, it will be very useful optically and electrically. 1) However, until now, a triazine cyclic polymer that forms a two-dimensional plane has not been synthesized.

本発明の化合物が生成する。The compound of the present invention is obtained by reacting the above compound with citric acid.The citric acid used in the present invention is nitric acid, hydrochloric acid,
When treated with hydrofluoric acid, sulfuric acid, etc., whose concentration is preferably higher than IN, and whose concentration is less than IN, almost no changes in elemental analysis values, IR, and X-ray diffraction patterns as described below will be observed. First, as shown in Figure 7, although there is a slight increase in fluorescence intensity, the basic structure remains almost unchanged.
On the other hand, when treated with a highly concentrated acetic acid such as ION, a compound of the present invention having different elemental analysis values, IR, and Xli diffraction patterns and different from the raw material is produced.
絋酸の使用量は、絋酸ｌｏｏｍ ｌに対し、原料の窒化
炭素約３ｇ以下の量が好ましい、３ｇ以上添加した場合
均一混合できず、均一な組成を存する酸処理物が生成し
ない。The amount of acetic acid to be used is preferably about 3 g or less of carbon nitride as a raw material per 1 a room of acetic acid. If more than 3 g is added, uniform mixing will not be possible and an acid-treated product with a uniform composition will not be produced.

５〜２４時間保つ、０．５時間より少ない場合は均一な
反応物が生成せず、２４時間以上保っても生成物は変わ
らず、経済的でない。The reaction temperature is not particularly limited, but from the viewpoint of ease of operation, it is preferably around room temperature, and after the reaction, the reaction temperature is 0.
If the reaction time is kept for 5 to 24 hours, a homogeneous reaction product will not be produced if it is kept for less than 0.5 hours, and the product will not change even if kept for more than 24 hours, which is not economical.
反応が終了した後、生成物を濾過し、濾液が中性になる
まで洗浄し、１００°Ｃ以下で恒量になるまで十分乾燥
する。生成した酸処理物は、元の窒化炭素が黄白色なの
に比較して、白色となる。After the reaction is completed, the product is filtered, washed until the filtrate becomes neutral, and thoroughly dried at 100°C or less until a constant weight is reached. The acid-treated product produced is white in color compared to the yellow-white color of the original carbon nitride.
得られた化合物の構造および物性について、種々の分析
装置により得られた結果を基に述べていくが、これらは
いずれも硝酸処理により得られたものである。The structure and physical properties of the obtained compound will be described based on the results obtained using various analytical devices, all of which were obtained by treatment with nitric acid.

ることがわかる。First, Figures 1 and 2 show the results of X-ray diffraction. Figure 1 shows the carbon nitride before treatment, and Figure 2 shows the result after treatment with nitric acid. It can be seen that the diagram becomes a little broader, indicating that it has become amorphous (lower molecular weight).

The absorption indicating the groups increases, indicating that these groups are present in the product. In this case, an increase in the absorption of NO2 groups was observed due to the treatment with nitric acid, but no NO□ groups were detected when other nitric acids were used.

熔解することからもわかる。FIG. 5 is a diagram showing the thermal stability of the acid-treated product.
At around 200°C, weight loss appears to be due to adhering water or detachment of Go, followed by weight loss at around 200°C due to decomposition or sublimation of the product itself, and 70°C.
It reaches almost 100% near 0'C. From this, the compound obtained by the acetic acid treatment has a molecular weight lower than that of one crystal of the raw material, which has a molecular weight of 10,000 or more, and the -- part of the terminal group is 0. or NO2
It appears that it has been replaced with a new one. This can be seen from the fact that while the original raw material can be isolated as a membrane, the acid-treated product is partially dissolved in concentrated acid.
また本発明の特徴は、第６図、第７図で示されるように
螢光特性に優れていることである。この螢光特性の測定
は３６５ｎ鳳を励起光として測定した。Further, a feature of the present invention is that it has excellent fluorescent properties as shown in FIGS. 6 and 7. The fluorescence properties were measured using 365n light as excitation light.

にわかる。この螢光は青色の光であり、このような優れ
た螢光特性を持つ酸処理物は種々の有用な用途が考えら
れる。Figure 6 shows carbon nitride, which is a raw material compound (indicated by a dotted line).
The emission spectrum of ION treated with nitric acid (indicated by the solid line) shows that the wavelength of the nitric acid-treated product shifts to lower wavelengths compared to the raw material carbon nitride, and the intensity is thicker (increased). Figure 7 shows the concentration of treated nitric acid, the luminescence intensity, and the half-width of the luminescence peak.
Treatment of N with nitric acid increased the luminescence intensity by about 4 times, and the half-width was 37.
4, the width of the emission wavelength is narrow due to the compound of the present invention,
Moreover, it can be similarly seen that a fluorescent spectrum with high intensity can be obtained. This fluorescent light is blue light, and acid-treated products with such excellent fluorescent properties can be used for various useful purposes.
さらに、本発明の酸処理物を熱処理した際の蛍光特性に
ついて検討したが、やはり熱処理の温度によって蛍光強

した。Furthermore, we investigated the fluorescence characteristics when the acid-treated product of the present invention was heat-treated, but the fluorescence intensity decreased depending on the temperature of the heat treatment, and even with ION's nitric acid treatment,
The strength of the material treated at 00°C was lower than that of the original carbon nitride.
以上、本発明を実施例により詳細に説明する。The present invention will now be described in detail with reference to Examples.
実施例１
ＩＯＮの硝酸１００■ｌに窒化炭素０．３ｇを加え、１
２時間攪拌し、濾過、洗浄した後、約１００℃以下で乾

After stirring for 2 hours, filtering and washing, the mixture was dried at about 100°C or lower.

あり、そのＩＲスペクトルにより（第４図）により末端
部に０１１５とＮＯ□基を含んでいることがわかった。While the original polymer was yellowish-white to yellow, the color changed to white after treatment FI. The elemental analysis values of the product are shown in Table 1, and the composition of this product is C6NysH7,tJ, 1. T!
It was found from its IR spectrum (Fig. 4) that it contained 0115 and NO□ groups at the terminal end.

なることからもわかる。In addition, part of the polymer dissolves in concentrated acid, and 1. Since it passed through a Teflon filter paper with a pore size of c+m, it is thought that the molecular weight was lower than that of the raw material carbon nitride. This can also be seen from the fact that the peaks in the X-ray diffraction diagram shown in FIG. 2 are somewhat broad.
