الاصطناع والخواص الضوئية لأصباغ مايثين مكونة من تكاثف كنوفيناجل لألدهيد عطري مع 1- ثنائي سيانوميثيلين اندان (2) أعطى مجموعة جديدة من الأصباغ (5a-k) لها امتصاص في المجال من 490-593. وجد أن المستبدلات في الحلقة العطرية للألدهيد لها تأثير كبي على قمم الامتصاص في المجال المرئي. زيادة قطبية المذيب لها تأثير على موقع الامتصاص.
