Published data on the synthesis and structural modification of spiropyrans and bisspiropyrans and production of the heteroanalogs of spiropyrans are classified and analyzed. The chemical characteristics of spiropyrans, including complexation of the open-chain isomers and cyclic forms are examined. Special attention is paid to the photochromic characteristics of spiropyrans at interfaces between phases.

“…The peaks observed for different conduction states were analyzed by comparing the spectra calculated by density functional theory (Section 1 in the Supporting Information) and the literature. − It was concluded that the SMJs in Figure a,c corresponded to the SP and MC forms, respectively (Section 2 in the Supporting Information). In the SP form (Figure a), the vibrations at 1541 and 1639 cm –1 were assigned to the C–C stretching vibration of the benzene ring in the benzopyran substructure and the CC stretching vibration of the pyran ring, respectively.…”

The characterization of single-molecule structures could provide significant insights into the operation mechanisms of functional devices. Structural transformation via isomerization has been extensively employed to implement device functionalities. Although single-molecule identification has recently been achieved using near-field spectroscopy, discrimination between isomeric forms remains challenging. Further, the structure–function relationship at the single-molecule scale remains unclear. Herein, we report the observation of the isomerization of spiropyran in a single-molecule junction (SMJ) using simultaneous surface-enhanced Raman scattering (SERS) and conductance measurements. SERS spectra were used to discriminate between isomers based on characteristic peaks. Moreover, conductance measurements, in conjunction with the principal component analysis of the SERS spectra, clearly showed the isomeric effect on the conductance of the SMJ.

“…We have studied the structure and also the thermo-and phototransformation of spiropyran VI that is adsorbed on the surface of silver film with Raman spectroscopy (RS). The photocoloration reaction of VI could be presented as a sequence of structural transformations [7].…”

A series of spiropyrans possessing photochromic properties in solid state were investigated. UV irradiation (λmax=365nm) of the thin vacuum deposited spiropyran films results in conversion of the colorless form to the photocolored one. The reaction is photochemically and thermally reversible. The photochromic activity of the solid material and polystyrene matrix has been compared. Raman spectroscopy has been used for studying the influence of metallic surface on the adsorbed spiropyran layers.
