Aggregation-induced emission enhancement of chiral boranils

resumo

New boranils based on chiral benzylamines have been synthesized and their photophysical properties studied. These BF2-complexes exhibit a bright blue fluorescence in solution and in the solid state, and exhibit aggregation-induced emission enhancement. The chirality of the ligand, even if it is not directly located at the boron center, has consequences on the circular dichroism of the complexes.

agradecimentos

Thanks are due to University of Aveiro, FCT/MEC for the financial support to the QOPNA research Unit (FCT UID/QUI/00062/2013) and CICECO-Aveiro Institute of Materials (POCI-01-0145-FEDER-007679; FCT-UID/CTM/50011/2013), through national funds and where applicable co-financed by the FEDER, within the PT2020 Partnership Agreement, and also to the Portuguese NMR Network. This work was also supported by the Integrated Programme of SR& TD "pAGE - Protein aggregation Across the Lifespan'' (reference CENTRO-01-0145-FEDER-000003), co-funded by the Centro 2020 program, Portugal 2020, European Union, through the European Regional Development Fund. PV thanks the FCT for a doctoral grant (SFRH/BD/99809/2014).
