DOI: 10.1016/j.bioorg.2021.105221
Abstract: Three barbiturate squaraine dyes derived from indolenine or benzothiazole, with different barbituric acid derivatives were prepared, characterized and photophysically evaluated by standard spectroscopic methods. As expectable for squaraines, these dyes showed narrow and intense absorption… read more here.

DOI: 10.1016/j.dyepig.2019.107977
Abstract: Abstract The intense and tunable emission of squaraine dyes is highly desirable, but it suffers from nonfluorescent aggregation and intrinsic chemical instability thus restricts its applications. Herein, incorporating benzocaine we synthesized two typical 1,3-SQs, namely… read more here.
