🔹 RMSs based on protein-derived chromophores, including:
▪️ Rhodopsin-like systems (retinal Schiff bases)
▪️ GFP-inspired systems (fluorescent protein motifs)

These designs improve aqueous compatibility and shift absorption into the bio-optical window.

🔹 Indigoid RMSs
Based on indigo or hemiindigo cores—robust, versatile scaffolds with tunable photochemistry.

We focus on rotary molecular systems (RMSs) that combine synthetic motor fragments with heterocycles inspired by biological chromophores.

We classify 3 main families:

🔦 Light is a perfect trigger for molecular systems: clean, precise, and tunable.
But shifting from UV to visible/NIR activation—while keeping efficiency, solubility, and biocompatibility—is not trivial.

So, what’s the strategy?
