Abstract AR
الاصطناع و الخواص الضوئية لأصباغ مايثين مكونة من تكاثف كينوفيناجل لألدهيد عطري مع 1-ثنائي سيانوميثيلين اندان (2) أعطى مجموعة جديدة من الأصباغ (5 a-K) لها امتصاص في المجال من 490-593 nm.
وجد أن المستبدلات في الحلقة العطرية للألدهيد لها تأثير كبير على قمم الامتصاص في المجال المرئي.
زيادة قطبية المذيب لها تأثير على موقع الامتصاص.
Abstract EN
The synthesis and the absorption properties of methine dyes formed by Knoevenagel condensation of aromatic aldehydes with 1-dicyano-methyleneindane (2) afforded novel series of dyes (5a-k) absorbing in the region of 490-593 nm.
The substituents on the aromatic aldehyde have remarkable effects on the visible absorption maxima of the new dyes.
Increasing the solvent polarity had pronounced effects on the absorption maxima.
