The impact of donor and π-spacer on linear and non-linear optical (NLO) properties was
investigated by designing and synthesizing dyes having diethylamino coumarin and …

Herein, we have evolved a new and efficient procedure for the synthesis of 3-(2-(4-
bromophenyl) hydrazone)-2, 4-chromandione BPHC via the cyclization of (4-bromo …

A metal-free and mild, photoinduced decarboxylative 4-position alkylation of coumarins has
been reported. Photoinduced single electron transfer has been initiated by utilizing the …

methyl umbelliferone compound is synthesized from resorcinol with ethyl acetoacetate
under ultrasound irradiation as an assistant of reaction. The coumarin derivative, COM-ester …

This article presents a simple and effective method to produce a heterojuction photodiode
based on coumarin doped bismuth oxide (Bi 2 O 3) composite. The photoresponse …

The fluorescence coumarin derivatives were synthesized by an efficient one-pot, three-
component reaction in 80–90% yields. These fluorescence dyes exhibited high fluorescent …

In this paper we present the optical properties of heterocyclic azo dyes containing polymers
thin films. From spectroscopic ellipsometry combined with transmittance measurements we …

The tandem inert α-C–H and C–N bond activation of amides represents a highly valuable
but challenging transformation in organic synthesis. Herein, a simple rare earth metal amido …

In this paper, we show that the optical properties such as extinction coefficient, refractive
index, optical conductivity and optical energy band gap of aminoazobenzene and …

During this study, a novel organic semiconductor material comprising coumarin and
chromone moieties was synthesized via a facile route. Thin films of the synthesized powder …
