The present disclosure provides a new series of compounds exhibiting high fluorescence quantum yields in the solid state. In one embodiment, the compounds include a series of 2,3,4,5-tetraphenylgermoles with the same or different 1,1-substituents. In another embodiment, substituted germafluorenes, germa-fluoresceins/rhodamines, and germapins are described. These germanium heterocycles possess ideal photophysical and thermostability properties, which makes them excellent candidates for chemical or biological sensors, host materials for electroluminescent devices and solar cells, and emissive and for electron-transport layer components in organic light emitting diode devices,

The synthesis and characterization of a series of six new highly fluorescent 2,7-alkynyl(aryl)-3,6-dimethoxy-9,9-diphenylsilafluorenes was investigated utilizing a modified multi-step synthetic pathway in which the final step utilizes palladium-catalyzed cross-coupling conditions to incorporate a variety of conjugated – alkynyl(aryl) groups at the 2,7-positions. These new compounds were characterized

Described herein are luminescent sila- and germafluorenes. Also described herein are methods of making and using sila- and germafluorenes. The position and the type of substituent impact the absorption and emission properties in solution and in the solid-state and subsequently influence the role of sila- and germafluorenes as biosensors.

We report the synthesis and excited-state intramolecular proton transfer (ESIPT) properties of three tris(N-salicylideneaniline)-based (TSA) imine-linked porous organic polymers (POPs) containing C3-symmetric 1,3,5-triarylbenzene (TAB), -tristyrylbenzene (TSB), and -tris(arylethynyl)benzene (TAE) monomer units. The TSA–POPs are fluorescent in the solid-state and responsive to Cu2+ and Pd2+.
,3‐dionate anion, X = 1, 2, 3] to afford corresponding Eu(III)‐containing polymer complexes. The resulting achiral polymer complex P‐2 (X = 2) can exhibit strong circular dichroism (CD) response toward both N‐Boc‐l and d‐proline enantiomers. The CD signal was preliminarily attributed to coordination induction between chiral N‐Boc‐proline and the Eu(III) complex moiety. The linear regression analysis
