It is found that the structure of diarylthieno 2.3-[3,4-b] pyrazine analogs (TPi with i = 1–5) is planar in these excited states. The S1/S0 electronic excitation is characterized as a highest occupied molecular orbital (HOMO) to lowest unoccupied molecular orbital (LUMO) transition and...
Schematic comparison between crystalline SiO2(quartz) and amorphous SiO2(glass). The atomic structure primarily affects the chemical, physical, thermal, electrical, magnetic, and optical properties. 1.1.2.2 Microstructure The term “microstructure” is used to describe the arrangement of phases and ...
In addition to the double helical structure of DNA, the genome is known to fold into a variety of noncanonical three-dimensional structures that offer unique opportunities for small molecule binding1,2. Molecules that recognize specific DNA folds that are scarce in the genome could be used to al...
