In this study, a new series of (4-(2, 7-dichloro-9H-fluoren-4-yl) thiazol-yl) acetamide
derivatives was synthesized, and the new heterocycles were completely characterized …

In the present study, the thermal 1, 5-electrocyclization back reaction from betaines (colored
forms) to dihydroindolizines (DHIs, colorless) was studied in seven organic solvents with …

Novel photochromic dihydroindolizines (DHIs) bearing different alkyl and cyclic alkyl ester
group (region B) were prepared via electrophilic addition of fluorene spirocyclopropenes …

A new class of thermochromic polynorbornene with pendent spiropyran moieties has been
synthesized. Functionalization of norbornene monomers with spirobenzopyran moieties has …

Representatives of visible-light-switchable nitrile-rich negative T-type photochromes (NRP)
were synthesized. The temperature effect on the thermal relaxation of the photoinduced form …

Twelve new photochromic materials based on dihydroindolizine (DHI) systems were
synthesized using mechanochemical reaction strategy in one-pot solid state reaction with …

A new mechanochemical synthetic strategy for the synthesis of novel tetrahydroindolizines
(THIs) photochromes incorporating different substituents in both regions B (ester part), and …

A method for the selective synthesis of 9-substituted fluorenols (FOLs) was developed by
suppressing intermolecular cyclization and promoting intramolecular C–H functionalization …

Herein, eighteen novel photochromic tetrahydroindolizines (THIs) have been successfully
prepared using a well-established mechanochemical synthetic approach. These products …

A new category of photochromic dihydroindolizines (DHIs) incorporating substituted 2, 7-and
4-substituted tetrazole and oxadiazole moieties in the fluorene skeleton (region A) were …
