Curved Nanographene
In article number 2212064, Sergio Ramírez‐Barroso, David García‐Fresnadillo, Inés Corral, Nazario Martín, Reinhold Wannemacher, and co‐workers scrutinize the photophysics of curved nanographenes. The intricate topography of their potential energy surfaces facilitates multiple and non‐Kasha emission from singlets and triplets and TADF phenomena, which are expected to bring about...
The intriguing and rich photophysical properties of three curved nanographenes (CNG 6, 7, and 8) are investigated by time‐resolved and temperature‐dependent photoluminescence (PL) spectroscopy. CNG 7 and 8 exhibit dual fluorescence, as well as dual phosphorescence at low temperature in the main PL bands. In addition, hot bands are detected in fluorescence as well as phosphorescence, and, in the narrow...
