1：Experimental Design and Method Selection:

The study involved synthesizing homochiral and heterochiral AlaNDI-Cd SCNs via solvothermal reactions using naphthalene diimide enantiomers and cadmium iodide. Chirality was used as a tuning parameter to control morphologies. Doping with hydrazine vapor was employed to enhance conductivity and photoresponsivity. Theoretical studies included DFT calculations and Monte Carlo simulations to understand formation energies, electronic structures, and adsorption mechanisms.

2：Sample Selection and Data Sources:

Samples included homochiral (R)- and (S)-AlaNDI-Cd, and heterochiral (Rac)-AlaNDI-Cd micro-/nanocrystals synthesized from enantiopure ligands and racemic mixtures. Data were obtained from material analyses (e.g., SEM, UV-Vis, ESR, XRD) and device measurements.

3：List of Experimental Equipment and Materials:

Equipment included stainless-steel tubes with Teflon liners for solvothermal reactions, SEM for morphology characterization, UV-Vis-NIR spectrophotometers (Cary 5000, Cary 6000i), spectrofluorometer (FP-6500, JASCO), spectropolarimeter (J-815, JASCO), ESR spectrometer (Bruker Biospin A200), single crystal X-ray diffractometer (Bruker APEX II QUAZAR), elemental analyzer (Elementar vario MICRO cube), and parametric analyzer (Keithley 4200-SCS). Materials included CdI2, H2AlaNDI ligands, DMF, hydrazine, silicon wafers with SiO2, Cr/Au electrodes.

4：Experimental Procedures and Operational Workflow:

Synthesis involved stirring CdI2 and ligands in DMF, sealing in tubes, and heating at 120°C for 72 h. Devices were fabricated by drop-casting dispersed crystals on pre-patterned electrodes and annealing. Electrical measurements were conducted in ambient and N2 conditions. Doping was performed by exposing devices to hydrazine vapor for 5 min. Material analyses included UV-Vis, CD, ESR, TGA, BET, FT-IR, PXRD, and single crystal XRD.

5：Data Analysis Methods:

Electrical conductivity was estimated using the two-probe method. Rise and decay times were fitted using exponential equations. DFT calculations used DMol3 with PBE functional and DNP basis set for energy and DOS analysis. Monte Carlo simulations used Sorption program with Universal forcefield for adsorption studies.
