Hybrid materials comprising diamond nanoparticles (ND) and oligo(phenylenevinylenes) (OPVs) have been synthesized by the covalent linking of acid-functionalized ND and OPV-amine. Chromophore-functionalized ND particles with long alkyl and pi-conjugated groups are readily dispersed in various organic solvents without any precipitation after several hours. A careful study of the properties of the hybrid materials revealed an aggregation-induced energy transfer from the blue fluorescent nanodiamonds to green emitting OPVs. At very low concentrations the hybrid emits in the blue region, but as the concentration is increased a gradual transition from blue to green emission occurs. Competitive processes such as aggregation-induced enhanced emission and self-absorption have been ruled out and a molecular picture of the phenomenon is proposed. This strategy can open a plethora of new avenues for fluorescent nanodiamonds in optoelectronics and light harvesting apart from bio-imaging.
