Photochemistry provides green alternatives to traditional reaction conditions and opens up routes toward products that are otherwise difficult to make. … Webof photobasicity in quinolines. In section II we will show our experimental work that quantifies pre-association and threshold for excited state proton transfer. We will briefly discuss proposed strategies to overcome the limitations posed by these problems. In section III we will discuss that while increasing the conjuga-
