“…On the other hand, the UV-vis transmission spectrum recorded from a bulk solution of ( R,R,M )- 1 in dichloromethane displayed a significantly different shape, with the mentioned five absorption bands as expected from a non-preferred orientation corresponding to ( R,R,M )- 1 molecules in solution. 55 Remarkably, the band centred at ca. 317 nm showed the highest intensity for the bulk solution but appeared as a small shoulder for the UV-vis spectra recorded at interfaces, thus confirming the relevance of the orientation of the ( R,R,M )- 1 molecules when analysing the UV-vis spectra (Fig.…”
