Recently I am researching about MALONONITRILE; FLUOROPHORES; FLUORESCENCE; DYES; RED, Saw an article supported by the Russian Foundation for Basic ResearchRussian Foundation for Basic Research (RFBR) [16-33-60156 mol_a_dk]. Formula: C7H13NO2. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Fedoseev, SV; Belikov, MY; Ievlev, MY; Ershov, OV. The CAS is 177-11-7. Through research, I have a further understanding and discovery of 1,4-Dioxa-8-azaspiro[4.5]decane
The first representatives of D-pi-A chromophores containing a hydroxytricyanopyrrole (HTCP) acceptor and N,N-disubstituted aminophenyl donor were synthesized. The obtained molecules include reactive NH- and OH-fragments allowing the photophysical properties of the chromophores to be tuned, which is not possible for the well-known chromophores of the tricyanofuran (TCF) and tricyanopyrrole (TCP) series. The absorption properties of the synthesized HTCP-chromophores with a p-aminophenyl electron donor substituent were thoroughly studied.
About 1,4-Dioxa-8-azaspiro[4.5]decane, If you have any questions, you can contact Fedoseev, SV; Belikov, MY; Ievlev, MY; Ershov, OV or concate me.. Formula: C7H13NO2
