Biphenylene-bridged mesostructured organosilica as a novel hybrid host material for Ln(III) (Ln = Eu, Gd, Tb, Er, Yb) ions in the presence of 2-thenoyltrifluoroacetone

Jean-Claude Bünzli

A hierarchically ordered 4,4'-biphenylene-bridged mesoporous organosilica framework (Bp-PMO) has been synthesized with the aim of using it as a new hybrid host for Ln(III) ions. A series of novel organic-inorganic luminescent hybrid materials have been obt ...
