Description
本發明係關於呈具有2-經取代1,3-二酮之金屬錯合物形式之新穎前驅物及其製備方法。本發明另外係關於其用於製造薄金屬氧化物層之用途。後者係極寬範圍之具有各種功能之電子組件及裝置中之成份。
藉由施加溶液或分散液來製造功能陶瓷層提供許多技術優點,例如成型製程。端視擬塗覆基板及擬沈積氧化層,已研發極寬範圍之製程及多種技術以允許製造二維亦及結構化塗層。可(例如)藉由旋塗、噴塗或噴墨印刷施加用作用於形成層之起始材料之化學組合物。與高真空技術相比,該等施加方法通常在設備方面較不複雜且有利地更適用於連續生產線,從而更容易地促進工業規模之性能。
基本上,兩種不同途徑可用於製備適宜塗覆溶液或分散液。
一方面,可將擬施加之用於形成氧化物層之適宜顆粒轉化成分散液且添加添加劑(例如液化劑、穩定劑、黏合劑或消泡劑)。在將分散液施加於基板上並乾燥之後,需要燒盡有機添加劑。另一選擇為,可採用適宜化學化合物之溶液來用作用於擬製造氧化塗層之前驅物。
該等溶液通常較顆粒分散液具有較長存架壽命及較大穩定性。在施加至基板之後,此時需要藉由熱處理轉化成期望氧化物。
兩種製程之共同特徵在於,性能所需溫度在數百度之範圍內延伸。
然而,為製造複雜組件,通常不期望在極高溫度下進行處理,此乃因此限制了擬塗覆基板之選擇且可發生界面處之干擾反應及互擴散。在過去已採納減小製程溫度之各種方式。除優化製程參數外,可在使用前驅物之情形下對金屬錯合物中配體之分子骨架進行化學改質。
然而,藉由自溶液施加且隨後熱處理自前驅物製造功能氧化層仍受限於其應用範圍。為自溶液沈積,需要前驅物在適於塗覆之溶劑中具有良好溶解性、溶液在環境及塗覆條件下具有穩定性、基板由溶液潤濕且在窄溫度範圍中具有最低可能轉化溫度。由此通常不能使用通常用於真空製程中(例如CVD(化學氣相沈積)製程中)之前驅物,此乃因此製程使用熱穩定且易於昇華之化合物。與之相比,為自溶液進行沈積,不期望在轉化成氧化層期間、尤其在多元或多相系統之情形下發生極微小昇華,此乃因較難以形成所定義組合物。
迄今為止所使用之前驅物群係呈所謂的席夫鹼(Schiff's base)(「肟鹽」)、尤其甲氧基亞胺基丙酸之縮合產物形式之配體系統。該等化合物之使用提供許多關於處理、膜形成及沈積膜後處理之優點。因此,可(例如)在熱轉化之後製造可用於薄膜電晶體中之半導電性層。除較高分解溫度外,使用此類化合物之缺點在於,難以在並不由鹼金屬或鹵化物離子痕量污染下進行製備。另外,用於席夫鹼(亦即α-酮酸及O-烷氧基胺)之縮合反應之起始材料僅可改質至受限程度且並無重大成果,此乃因需要大量合成步驟,然而,此將得到低產率。
本發明目標由此係提供製備適宜前驅物之製程,其可簡單且可
靠地實施,其避免所闡述缺點且其可藉助容易地衍生之配體系統實施,其中可以簡單方式在最低可能溫度下將以此方式製得之前驅物轉化成相應金屬氧化物,且並不形成顯著比例之必須藉由熱處理排出之有機殘餘物。本發明目標由此亦係提供易於分解以得到揮發性成份之配體。
現已發現,可藉由通式(I)之具有2-經取代1,3-二酮之新穎金屬錯合物來達成本發明目標:Ml[R1-CO-C(H)mX-CO-R2]n, (I)
其中M 表示選自鋅、銦、鎵、錫、鋁、鋯、鈦及鉿之群之金屬原子,l 表示1或2,在形成簇之情形下2,m 表示0或1,n 表示1、2、3或4,在形成簇之情形下>2,R1、R2、 彼此獨立地表示具有1至8個C原子之烷基,具有3至7個C原子之環烷基,具有1至8個C原子之烷氧基或胺基、NHR3、NR3R4,其中R3、R4彼此獨立地表示具有1至8個C原子之烷基或具有3至7個C原子之環烷基,且X 表示H、羥基亞胺基、硝基、磺酸基(包含具有1至8個C原子之-SO2-烷基)、磷酸根基(包含-PO(O-R)2,其中R=具有1至8個C原子之烷基或具有1至8個C原子之烷氧基)、錫烷基-SnR3(其中R=具有1至8個C原子之烷基)、巰基-SR(其中R=H、具有1至8個C原子之烷基或具有3至7個C原子之環烷基)、鹵基(例如F、Cl、Br或I)或類鹵基(例
如-CN、-N3、-OCN、-NCO、-CNO、-SCN或-SeCN),尤其係如下1,3-二酮:其中R1、R2、R3及R4彼此獨立地表示甲基、乙基、丙基、丁基、戊基、環丙基、環丁基、環戊基、環己基、甲氧基、乙氧基、丙氧基且在R1及R2之情形下表示胺基。該等1,3-二酮中之X或HX較佳地採用含義羥基亞胺基、硝基、磺酸基(包含具有1至8個C原子之-SO2-烷基)、鹵基(例如F、Cl、Br或I)或類鹵基(例如-CN、-N3、-OCN、-NCO、-CNO、-SCN或-SeCN)。自1,3-二酮之此群,選自硝基丙二酸二甲基酯、丙二酸羥基亞胺基二甲基酯及硝基丙二酸二醯胺之群之化合物尤其適於達成本發明目標。該等1,3-二酮作為配體與選自鋅、銦、鎵、錫、鋁、鋯、鈦及鉿之群之金屬原子M形成通式(I)之金屬錯合物,其即使在低溫下亦可轉化成相應金屬氧化物。若期望,則亦可以相同方式製備未列示於本文中之其他金屬之相應錯合物。因本文所呈現配體之性質,該等金屬錯合物以相同方式具有低分解溫度且可以相同方式用作本文所闡述之錯合物。實施例展示,選自丙二酸硝基二甲基酯、丙二酸羥基亞胺基二甲基酯及硝基丙二酸二醯胺之群之通式(I)之1,3-二酮之金屬錯合物尤其適用於至相應金屬氧化物的期望轉化,且形成薄、視情況陶瓷氧化物層並分解配體以得到揮發性成份。
本發明之通式(I)之金屬錯合物可呈簇形式,其經由金屬錯合物分子之締合且視情況釋放個別配體形成。相應地,該等簇中之數值1採用大於或等於2之值。數值n相應增加且大於2。
為實施製造薄金屬氧化物層之製程,將一或多種如上文所闡述之金屬錯合物視情況在水存在下溶解或分散於適宜溶劑或溶劑混合物中,藉助濕式塗覆將所獲得溶液或分散液(視情況向其中添加選自液化劑、穩定劑、黏合劑及消泡劑及視情況其他添加劑之群之其他添加
劑)施加至擬塗覆基板表面上,乾燥,且在另一步驟中,藉助在烘箱中、於熱板上加熱或藉助藉由UV、IR或雷射進行輻照來將所施加金屬錯合物層轉化成呈薄層形式之金屬氧化物。
為製備溶液或分散液,選自甲氧基乙醇、二甲基甲醯胺及二甲氧基乙烷之群之溶劑(其可採用純形式或混合物形式,視情況亦在水存在下)尤其適宜。
可在此製程中藉助旋塗、浸塗、噴塗、凹版印刷、噴墨印刷或柔性版印刷將包括金屬錯合物之溶液或分散液施加至基板表面上。若包括相應金屬錯合物之溶液或分散液包括選自甲氧基乙醇、二甲基甲醯胺及二甲氧基乙烷(個別地或呈混合物形式)及視情況水之群之溶劑,則製程尤其有利。可令人吃驚地藉由在低於同等已知製程之溫度下、較佳地在150-350℃範圍之溫度下加熱及煅燒來轉化以此方式施加並乾燥成薄氧化物層之金屬錯合物層。以此方式,可根據本發明以易於實施之製程來製造金屬鋅、銦、鎵、錫、鋁、鋯、鈦及鉿或其他適宜金屬之薄陶瓷氧化物層。特定而言,可此方式製造氧化物以純形式或混合物形式或混合氧化物形式存在之層。
若需要形成足夠厚或緻密之均質層,則在加熱及煅燒之前向基板表面多次施加溶液或分散液,且每一層個別地乾燥及加熱。
本文所提供之製程普遍適用,且含有呈通式(I)之1,3-二酮形式之配體之新穎金屬錯合物可用於製造電子組件(例如電容器或薄膜電晶體)、光伏打裝置、半導體技術中的薄金屬氧化物層或用作抗刮擦或抗反射層。然而,該製程亦適於使用本發明之該等金屬錯合物來製造太陽能電池、平板螢幕及觸控螢幕中之薄金屬氧化物層或用作場效電晶體中之半導體。

實驗令人吃驚地展示,具有通式(I)之2-官能化1,3-二酮之金屬錯合物之新穎種類材料:Ml[R1-CO-C(H)m X-CO-R2]n, (I)
其中M 表示選自鋅、銦、鎵、錫、鋁、鋯、鈦及鉿之群之金屬原子,l 表示1或2,在形成簇之情形下2,m 表示0或1,n 表示1、2、3或4,在形成簇之情形下>2,R1及R2 彼此獨立地表示具有1至8個C原子之烷基,具有3至7個C原子之環烷基,具有1至8個C原子之烷氧基及/或胺基、NHR3或NR3R4,其中R3
及R4彼此獨立地表示具有1至8個C原子之烷基或具有3至7個C原子之環烷基,且X 表示H、羥基亞胺基、硝基、磺酸基(包含具有1至8個C原子之-SO2-烷基)、磷酸根基(包含-PO(O-R)2,其中R=具有1至8個C原子之烷基或具有1至8個C原子之烷氧基)、錫烷基-SnR3(其中R=具有1至8個C原子之烷基)、巰基-SR(其中R=H、具有1至8個C原子之烷基或具有3至7個C原子之環烷基)、鹵基(例如F、Cl、Br或I)或類鹵基(例如-CN、-N3、-OCN、-NCO、-CNO、-SCN或-SeCN),尤其適用於所闡述需求。此同樣適用於通式(I)之該等金屬錯合物之簇,該等簇係經由締合且視情況釋放配體所產生,從而得到各自彼此獨立地採用大於或等於2之值之l及n。在該等簇中,l可採用數千之值。同樣亦相應地適用於n。通式(I)之金屬錯合物之簇中之l通常表示2至160之數值。端視所締合金屬錯合物分子之數量,n之數值有所變化。出於本文所提出之目的,金屬核l之數值在2至40之範圍內之簇較為適宜。
為合成金屬錯合物,可自多種配體進行選擇,此乃因2位中之1,3-二酮[R1-CO-CH2-CO-R2,其中R1、R2=如上文所列示之烷基、烷氧基及/或胺基(NH2、NHR3或NR3R4)]之官能化可藉由極寬範圍之基團X或HX以簡單方式進行,二者係用於2位中之基團鍵結係藉由單鍵或藉由雙鍵發生之相應二酮。需要較少步驟來合成,其同時得到良好產率。如上文所列示,基團X及HX可為羥基亞胺基(=NOH)、硝基(-NO2)、磺酸基(-SO2(R))、磷酸根基(-PO(OCH3)2)、烷氧基(-OR)、錫烷基(-SnR3)、巰基(-SH或-SR)、鹵基(例如F、Cl、Br或I)或類鹵基(例如-CN、-N3、-OCN、-NCO、-CNO、-SCN或-SeCN),其中基團R可具有上文所給出之含義。
該等配體通常可藉由蒸餾、昇華或重結晶充分純化。
因配體之酸性,金屬錯合物之後續合成可使用金屬化合物本身來實施,其形成具有所選配體系統(例如金屬之烷氧化物、烷基化物、羧酸鹽或碳酸鹽)之期望錯合物。此使得能夠大大減少或完全預防由鹼金屬或鹵化物所致之污染。然而,原則上同樣可使用其他金屬化合物,例如鹵化物、硝酸鹽或其他鹽。用於製備錯合物系統之適宜金屬化合物尤其係金屬鋅、銦、鎵、錫、鋁、鋯、鈦及鉿之烷氧化物、烷基化物、羧酸鹽、鹵化物或碳酸鹽。對於錯合物中所存在金屬元素之限制僅存在於即使在錯合物中仍具有強氧化或還原性質之罕見氧化態之情形下。後者不適用於本發明目的。
根據本發明,所製備金屬錯合物得到相應金屬氧化物之分解製程亦及由此分解溫度可由X或XH官能化之選擇亦及取代基R1及R2顯著影響。此外,根據本發明藉由對通式(I)之金屬錯合物中配體之取代基進行簡單改質來改良溶解性。此可能特定而言經由選擇R1及R2來進行,但特定而言亦經由引入適宜基團X或HX來進行。可經由取代基之適宜選擇來增加金屬錯合物之溶解性。同時,可經由取代基選擇來增加可採用之溶劑範圍。
所實施實驗展示,通式(I)之2-官能化1,3-二酮之本文所闡述金屬錯合物Ml[R1-CO-C(H)m X-CO-R2]n,可在令人吃驚地較低溫度下轉化成氧化物層。
如所展示,易於獲得之新穎前驅物通常適於自溶液沈積薄氧化層。由此在極為不同之區段中廣泛施加此類化合物係可能的。除用於製造電子切換元件(薄膜電晶體)外,其亦可用於光伏打裝置製程中或用於製造抗刮擦或抗反射層。
特定而言,以此方式在低溫下製得之氧化物層滿足(例如)在製造
場效電晶體中之半導體中功能層之高需求。
因此,本發明a)提供用於新穎金屬錯合物之合成途徑,該等新穎金屬錯合物可在較低溫度下轉化成呈薄層形式之相應金屬氧化物且釋放易於揮發性有機分解產物且b)提供呈金屬錯合物形式之新穎前驅物,其可用於可簡單及可靠實施之製程步驟中以製造場效電晶體及其他電子組件,c)使得該等新穎材料及金屬錯合物能夠用於工業領域中,例如用於光學應用中以製造抗反射層等或用作呈抗刮擦層形式之機械保護層。
可藉由自文獻及熟習此項技術者通常已知之方法來製備本發明配體及用作用於製造薄金屬氧化物層之前驅物之金屬錯合物。
因此,可藉由已知文獻製程來合成下列實例中所使用之配體及金屬錯合物。所採用之起始材料可為市售1,3-二酮[R1-CO-CH2-CO-R2,其中R1、R2=烷基、烷氧基及/或胺基(NH2、NHR3或NR3R4)]。同樣藉由自文獻已知之製程來實施2位中之官能化。
可根據由H.Adkins及E.W.Reeve(J.Am.Chem.Soc. 1938,60,1328-1331)闡述之實例來實施1,3-二酮(其中基團R1及R2具有含義烷基或烷氧基)之亞硝化。可藉由M.A.Whiteley(J.Chem.Soc.Trans. 1900,77,1040-1046)之方法或如由M.Conrad及A.Schulze在Ber.Deut.Chem.Gesell. 1909,42,729-735中所闡述來實施1,3-二酮(其中R1及R2具有含義胺基)之亞硝化。可藉由如下列參考文獻中所闡述之方法來實施1,3-二酮(其中R1及R2具有含義烷氧基)之硝化:D.I.Weisblat,D.A.Lyttle,美國專利第2,644,838號。亦可藉由A.L.Laikhter,V.P.Kisiyi,V.V.Semenov(Mendeleev Commun. 1993,3,20-21)之方法或藉

亦可藉由自文獻已知之該等方法來製備(例如)用於製造本發明之金屬氧化物層之實例中所闡述之配體。
如上所述,可使式(I)之所衍生1,3-二酮以簡單方式與上述金屬化合物進行反應以得到期望金屬錯合物,其可用作用於製造薄金屬氧化物層之前驅物。端視基團R1、R2及取代基X及HX,可藉由加熱至最高600℃之溫度(例如藉由使用UV、IR或雷射進行輻照)來將金屬錯合物轉化成金屬氧化物,其中所釋放之有機分解產物蒸發。就此而論,較佳係儘可能溶於水性系統中且在較低溫度下、尤其在150℃至350℃範圍之溫度下加熱後轉化成相應金屬氧化物之金屬錯合物。實驗已展示,就溶解性亦及轉化溫度而言,配體丙二酸2-硝基二甲基酯及丙二酸2-羥亞胺基二甲基酯之金屬錯合物尤其適宜。
為製造金屬氧化物層,首先視情況在水存在下將作為前驅物或中間體之本發明之金屬錯合物溶於具有適宜揮發性及黏度之溶劑(例如甲氧基乙醇、二甲基甲醯胺或二甲氧基乙烷)中。可藉由濕式塗覆且藉由已知方法(例如旋塗、浸塗、噴塗、噴墨印刷、柔性版印刷或凹版印刷)來施加至基板表面。自溶液之適宜塗覆方法由R.M.Pasquarelli等人闡述於Chem.Soc.Rev., 2011,40,5406-5441中。在乾燥之後於另一步驟中藉助在烘箱中或在熱板上加熱或藉助藉由UV、IR或雷射進行輻照來將所施加金屬錯合物轉化成期望氧化塗層,其中
根據本發明,氧化材料形成薄層形式。在特定情形下,為製造足夠厚之層,可重複施加溶液、乾燥及加熱之步驟數次。此處亦可使用不同金屬錯合物之溶液實施各種施加步驟,從而形成包括不同金屬氧化物之層。然而,亦可將兩種或更多種不同金屬錯合物溶於擬施加溶液中,從而在藉由加熱或煅燒轉化之後,獲得不同金屬之混合氧化物。
本說明使得熟習此項技術者能夠全面地應用及實施本發明。即使未進一步評論,亦可由此假定,熟習此項技術者將能夠以最寬範圍利用上述說明。
若有任何不清楚之處,則不言而喻,應考慮所引用之出版物及專利文獻。因此,將該等文件視為本說明之揭示內容之一部分。
