Aggregation Induced Emission (AIE) is a relatively young field of research that is radically changing the way we use fluorophores for "real-life" applications. In this novel photophysical phenomenon, chromogens that are not fluorescent in solution become highly emissive in the aggregate or solid state. Consequently, aggregation is no more a threat for fluorophore based application and priors test that relied on 'turn-off' mechanisms can now be transferred to more sensitive "turn-on" detection scheme. Here we will present new results obtained on a series of small AIEgen push-pull molecules whose emission span the visible spectrum. The aggregates are created and characterized inside microfluidic chips. This short paper will mainly focus on technical aspects of such measurements.
