First example of solid-state luminescent borasiloxane-based chiral helices assembled through N-B bonds

The reaction between differently substituted borasiloxanes and 2,5-bis(3-pyridylethynyl)thiophene provided the first example of luminescent borasiloxane-based chiral helices held together by N-B bonds. The starting building blocks and the helices were fully characterized, and the nature of the N-B bond rationalized by means of theoretical calculations.

Automated summary

The reaction between differently substituted borasiloxanes and 2,5-bis(3-pyridylethynyl)thiophene resulted in the formation of luminescent borasiloxane-based chiral helices held together by N-B bonds, which were fully characterized along with the starting building blocks. The nature of the N-B bond was rationalized through theoretical calculations.
