A crystalline and conjugated semiconductor thin film of poly(o‐phenylene diamine‐co‐m‐phenylene diamine) copolymer [PoPmP]TF with a thickness of 150 ± 3 nm is fabricated by physical vapor deposition technique (PVD). The copolymer is produced in an acidic solution using oxidative polymerization method. The ratio between the monomers and initiator is 1:1:2. The characterization of the obtained copolymer powder is carried out using different techniques includes Fourier‐transform infrared spectroscopy (FTIR), UV–Vis spectroscopy (UV–Vis), proton nuclear magnetic resonance (1HNMR), X‐ray diffraction analysis (XRD), and scanning electron microscopy (SEM). The structure and optical properties of the thin film were measured experimentally and computationally using DFT simulation. The obtained DFT data provide good proof for the electronic transition in zero‐dimensional [PoPmP] as a single crystal molecule. The obtained thin film presented encouraging outcomes to be a worthy applicant for polymer solar cell uses. This study provides valuable information on the nature and sources of defect formation and electronic transition in conducting doped copolymer which open the way for the application as an optoelectronic device.

The reverse mode polymer dispersed liquid crystal (PDLC) is an emerging smart window technology. Unlike traditional PDLCs, a reverse mode PDLC can be transparent and opaque in the absence and presence of an external electric field. This report provides a brief introduction to several reverse modes PDLC smart window technologies, focusing on polymer-stabilized liquid crystals (PSLCs). The systems based on electrohydrodynamic instability (EHDI) of liquid crystals have also been discussed. The working principles, mode of material design, and recent developments are presented for each technology. The current obstacles have also been pointed out. The prospects of smart windows have also been presented.

Inherent and incredible properties of liquid crystals (LC) such as optical and dielectric anisotropy make them special candidates for flat-panel display devices; bi-stable reflective displays; high-definition spatial light modulators; switchable windows; haze-free normal-and reverse-mode light shutter devices; projectors; optical, thermal and strain sensors; tuneable lenses; etc. Non-linear response of LC material to the applied electric field is very useful in the above-mentioned applications. When a low molecular weight LC material is doped in a high molecular weight polymer matrix to obtain polymer-dispersed liquid crystal (PDLC) films, it offers flexibility and mechanical strength (structural stabilization) to the composite films-PDLC devices. Depending upon the concentration of monomer/polymer, these composite films are classified as polymer-stabilized liquid crystal (PSLC), PDLC and holographic PDLC (HPDLC) films. Depending upon the process conditions, we get phase-separated randomly dispersed micron-sized LC droplets in a continuous polymer matrix. These nematic LC droplets exhibit light scattering transmission properties depending on their orientation, which can be controlled by external electric field. This chapter gives deep insight about operating principle, phase separation techniques involved, alignment of LC and controlling LC droplet morphology of PDLC films to obtain desired properties. In order to improve the optical efficiency and to obtain the desired result from PDLC films, various guest entities such as dye and nanomaterials are doped in the host LC material. This chapter also accounts for various possible LC dopants desired for improving the electro-optic (EO) and dielectric properties of PDLC devices. Various applications of PDLC composite films are also described in this chapter.
