This work reports on the search for highly efficient aluminum-based complexes for the synthesis of high molar mass polymacrolactones and their well-defined block copolymers with small ring lactones, ε-caprolactone and L-lactide.
Beyond just finding different optical “characteristics”, we found “specific functions” for each polymorph due to the rational design of a polymorphic and highly luminescent compound.
Synthesis of half-sandwich Ru and Fe complexes functionalised with alkynyl dihydropyrenes is described. Unlike the parent DHP ligand, several of the metal alkynyl dihydropyrenes showed evidence of photoswitching as a result of a higher barrier to thermal reversion.
Herein, we describe high quantum yields of organotin complexes in Me-THF at 77 K (ΦF 37 and 67%) due to the rotational fixation of a terephthalohydrazide bridge. PET bottle waste was used as raw material to synthesize ligand and tin complexes.
Non-planar and non-aromatic porphyrin(2.1.2.1) organopalladium complexes show singlet oxygen quantum yields as high as 56%, slightly lower than that of Ru(bpy)3Cl2 and some clinically evaluated porphyrinoid 1O2 sensitizers.
