In recent years, extensive research efforts have been made to develop novel p-conjugated materials including small molecules, oligomers, and polymers, and to use them in various applications such as organic-field effect transistors (OFET), photovoltaics, hole transfer materials (HTMs) in perovskite solar cells, organic light emitting diodes (OLEDs), etc. These materials offer a number of technological advantages over their inorganic counterparts, such as their low weight, low fabrication cost, foldability, and easy conformation onto non-flat surfaces. For the characterization methods, diverse spectroscopy measurements have been utilized to probe the photo response activity of these p-conjugated materials, e.g., absorption/emission spectroscopy, elastic scattering and reflection spectroscopy, laser spectroscopy, coherent or resonance spectroscopy, and nuclear spectroscopy.
To obtain high-performing materials, molecular design concept is critical. Optical and electrochemical properties, solubility, and the charge transfer ability, which are closely related to the spectroscopy characterization, can all be easily controlled through adjusting the molecular chemical structures and their neighboring molecular interactions. For instance, (i) enlarging the size of alky chains could enhance the materials’ solubility; (ii) increasing the p-conjugation system or introducing electron-rich and deficient unities on the polymer backbone could reduce the band gap or lead to bathochromic shift in the optical absorption; (iii) self-assembled or crystalline conjugated materials often show high charge transfer mobility.
The aim of the current Research Topic is to cover promising, recent, and novel research trends in the diverse spectroscopy studies on the p-conjugated materials including small molecules, oligomers, and polymers for various optoelectronic applications, such as OFETs, photovoltaics, OLEDs, etc. Areas to be covered in this Research Topic may include, but are not limited to:
-Development of p-conjugated materials
-UV-visible light sensitive p-conjugated materials
-NIR light sensitive p-conjugated materials
-High-performance p-conjugated materials-based optoelectronics
-Role of spectroscopy studies in probing charge transfer dynamics of p-conjugated materials
-Next generation light-activated p-conjugated materials
The types of manuscripts in this Research Topic are focusing on original research articles, perspectives and reviews (including mini reviews).
