Scheme 2.

The design of hydrophobicity and low lipophilicity NIR solid-state fluorochrome. (A) A de novo design strategy for developing solid-state fluorophores. (B) Solid-state fluorescent photographs of those fluorophores in the powder samples. (C) Diffusion experiments were conducted at the interface between water and dichloromethane (amphiphilic environment). All fluorescent photos were obtained under UV lamp excitation at 365 nm.
