Synthesis and photochromic properties of hybrid molecules based on fullerene C60 and 3,3′-(cyclopent-1-ene-1,2-diyl)bis(5-chloro-2-methylthiophene)

Synthesis, photo and acidochromic properties of spiropyran-containing methanofullerenes

“…In view of high sensitivity of initial spiropyrans to a broad range of external stimuli 10,23-30 and to pursue our research aimed at the development of efficient synthetic routes to new molecular switches based on fullerenes and photochromic compounds, [14][15][16][31][32][33] we investigated photochromic and acidochromic behaviors of methanofullerenes 2, 7-10, 18-24.…”

Photocontrolled organic field effect transistors based on the fullerene C60 and spiropyran hybrid molecule

“…In view of the above and as a continuation of our research towards the preparation and studies of properties of hybrid molecules based on fullerenes and photochromic compounds aimed at the design of more efficient and promising organic electronic devices, [13][14][15][16][17][18] we have fabricated and investigated a photocontrolled OFET containing pyrrolidinofullerene 1 as the active layer ( Fig. 1a).…”

Hybrid Molecules Based on Fullerene C60 and Dithienylethenes. Synthesis and Photochromic Properties. Optically Controlled Organic Field‐Effect Transistors

“…Previously (17), we demonstrated, in relation with spiropyrans, that the use of mixed fullerene and photochrome layers or hybrid molecules based on these compounds not only simplifies the OFET fabrication but also markedly enhances their performance characteristics in comparison with the devices in which the semiconductor and photoswitch were applied separately. The absence of published data on OFETs fabricated using hybrid molecules based on fullerene and diaryl(hetaryl)ethenes is probably due to the facts that the chemical binding of these compounds usually decreases the efficiency of photoisomerization or gives hybrid molecules devoid of photochromic properties (18)(19)(20)(21)(22). The introduction of a phenylethynyl or porphyrin spacer between the fullerene and dithienylethene molecules affords hybrid compounds in which the dithienylethene moiety efficiently undergoes reversible photoisomerization (23,24).…”
