A series of multifunctional coordination polymers based on terpyridine and zinc halide: second harmonic generation and two-photon absorption properties and intracellular imaging

Abstract

How to improve your image? Coordination polymer (CP) showed fascinating potential in optoelectronic optics but limited in bioimaging. Without doubt, it is very meaningful when CPs was first using in second-harmonic generation (SHG) imaging. Herein, through reasonable design and synthesis, a series of nonlinear optical CPs bearing very good one-photon excited fluorescence (OPEF), two-photon excited fluorescence (TPEF) and highly strong SHG properties have been presented. Further study demonstrated that the nanoscaled CPs show very strong SHG signals which have been applied in three-dimentional imaging of thick block tissue with higher spatial resolution through simultaneous multichannel nonlinear optical (NLO) imaging technology. After simply encapsulated by polymeric micelles, nanoscaled CPs successfully applied in the SHG bio-imaging within the living cells. This finding throws light on the design of nanoscaled NLO CPs and offers a simple avenue to develop novel effective exogenetic SHG imaging agents.
