Findings

OSPC-1b achieved the highest surface area of 909 m2 g–1 among OSPC materials.

OSPC-1b showed comparable electrochemical performance to OSPC-1a in Li-ion batteries.

Electrochemical properties of OSPC-0 were confirmed for the first time, aligning with predictions.

Abstract

Organically synthesized porous carbon (OSPC) is a subclass
of conjugated
microporous polymer materials that have shown potential applications
as anodes in ion batteries. However, a challenging, low-yielding,
multistep synthetic route (the A method) has hindered further exploration
of this exciting family. Here, OSPC-1 has been synthesized via an
alternative, efficient one-pot method from commercially available
reagents (the B method), hereafter referred to as OSPC-1b in contrast
to OSPC-1a, where it is synthesized via the A method. Characterization
revealed the same polymer structure and the highest surface area to
date of an OSPC (or OSPC analogue) family member for OSPC-1b with
909 m2 g–1. OSPC-1b was tested as an
anode for Li-ion batteries, demonstrating the same high capacity,
fast charging, resistance to degradation, and inhibition of the formation
of dangerous lithium dendrites as OSPC-1a. Furthermore, the electrochemical
properties of OSPC-0 were evaluated for the first time, agreeing with
previously predicted values, giving scope for the design and targeting
of specific properties.
