Experimental Skills and Techniques

• Experimental System Design with Synthesized Molecules:

- Heavy emphasis on tailoring donor (D) – acceptor (A) conjugated polymer structures, side-chain modifications, and halogen substitutions to optimize (opto)electronic properties.

• Thin-Film Fabrication and Processing w/ Interfacial Engineering:

- Studies of solvent/solid additives, rubbing/alignment methods, and miscibility/phase separation control to improve film morphology and device performance.

• Thin-Film Mechanics in Stretchable Systems:

- Use of photocrosslinkers, plasticizing additives, and strain analysis to achieve robust mechanical properties while retaining high charge mobility.

• Synchrotron X-ray based Analysis and Multi-scale Device Characterization:

- Techniques like GI(S)WAXS, UPS, XPS, NEXAFS, UV–vis absorption, RAMAN, FT-IR, NMR, TEM, SEM, POM with electrical and mechanical testing, and also in-situ operando measurements of charge transport under strain.
