Microflowers formed by complexation-driven self-assembly between palladium(ii) and bis-theophyllines: immortal catalyst for C–C cross-coupling reactions

Abstract

Bis-theophylline-palladium complex exhibit high catalytic activity in the C–C coupling reaction with excellent recyclability in the presence of NaCl.

Photoluminescent polymer micelles with thermo-/pH-/metal responsibility and their features in selective optical sensing of Pd(ii) cations

“…This color suggests the formation of a Pd( ii )/theophylline complex which shows absorption at wavelengths around 400–500 nm. 55 The sediments visualized by SEM are fibrous network entities which are likely formed by linking of the fibrously fused micelles. Perhaps, the post-added Pd 2+ cations chelate with the theophylline and imidazole residues which exist on the core surface and thus promote one-dimensional growth of inter-micellar fusion but do not destroy the micelles.…”
