Application of the nonlinearoptical materials to the optical and optoelectronic devices requires largesecond-ordernonlinearopticalproperty and thermal stability. 1,2 Much effort has been focused to optimize the physical properties of the donor -acceptor dipoles in order to meet these criteria. While there has been a great progress in improving these properties, it has become apparent that the

oriented nucleation sites, and ultimately organic branch microstructures with controllable branch sites were fabricated. The growth mechanism of these controllable single crystals with an angle of 140° between trunk and branch is attributed to the low lattice mismatching ratio (η) of 4.8%. These as-prepared hierarchical branch single crystals with asymmetrical optical waveguide characteristics have been
