- Abstract
Carbon‐chain dendritic polymers hold unique properties and promising applications. However, synthesizing carbon‐chain dendrimers, beyond conjugated ones, remains a challenge. Here, the use of the iterative single unit monomer insertion technique for synthesizing 2.5 generation partial‐carbon‐chain dendrimers (G2.5) is described, utilizing bismaleimide as the core, a maleimide–trithiocarbonate conjugate as the branching unit, and indene as the spacer unit, following a divergent growth strategy. The optimized conditions for synthesizing the maleimide–trithiocarbonate branching unit are a bismaleimide to trithiocarbonate ratio of 5:1 and a reaction time of 30 min. The structures are verified using 1H nuclear magnetic resonance, gel permeation chromatography, and matrix‐assisted laser desorption/ionization‐time of flight mass spectra. A four‐arm star polymer is then synthesized using the G2.5 as the core. This synthesis of a partial‐carbon‐chain dendrimer establishes a foundational step toward creating all‐carbon‐chain ones and may open new application avenues in material science.
