various important photothermalmaterials and their classification along with their working principle. Then, we highlight important aspects of the nanoscale architecture (i.e., size, shape, and composition) to enable maximum light-to-heat conversion efficiency. Finally, we discuss some of the recent
possessing well-engineered characteristics in terms of size, shape, and composition are regarded as potential candidates for diverse photothermal applications, including photothermal LFAs. Photothermalmaterials can be categorized into four main types, depending on their chemistry and light absorption

Introduction
With the rapid development of the world economy, global water shortages are occurring
. Photothermalmaterials (PTMs) applied to SSG include metallic materials, semiconductors, carbon-based materials, and conjugated organic materials [1][2][3][4]. Compared to metallic and inorganic PTMs, π-conjugated organic PTMs have advantages, such as a greater light absorption, easier synthesis, and
the initial temperature of water, c is the specific heat of water (4.2 J·g−1·K−1), Q is the sensible heat of water, HLV is the enthalpy of water vaporization, and Ein is the energy of the incident light.
