Abstract

Se preparan fluoreno-9-espiro-lactonas cromógeneas con la fórmula **(Ver fórmula)** en donde R1, R2, R3, R4 y E tienen significados definidos. Estos compuestos pueden obtenerse mediante diazotación y luego efectuando una reacción de cierre de anillo en el correspondiente precursor ftalida, furopiridina o furopirazina sustituida con amino primario. Los compuestos son cromógenos y pueden usarse en material de registro sensible a la presión y/o calor. Dan colores azules hasta verdes sólidos frente a la luz cuando reaccionan con co-reaccionantes que aceptan electrones. Las formas coloreadas exhiben absorción marcada en la región próxima del infrarrojo, que las hace particularmente útiles en sistemas de detección OCR (reconocimiento óptico de caracteres).
