Table 2. Melting temperature (T_m) and enthalpy change of melting (ΔH_m) of xerogels of initial ^a and annealed decarboxylated ^b samples of OAT-CO₂H-2n.

First heating initial sample	T _m (°C)	ΔH_m (J g^–1)	Second heating decarboxylated sample	T _m (°C)	ΔH_m (J g^–1)
OAT-CO₂H-6	100	21.0	OAT-H-6	117	20.3
OAT-CO₂H-8	132	25.0	OAT-H-8	137	24.8
OAT-CO₂H-10	149	29.9	OAT-H-10	149	27.2
OAT-CO₂H-12	155	30.7	OAT-H-12	154	24.8

^aXerogels were prepared from freeze drying of a p-xylene gel sample of gelator conc. = 25 mg mL^–1.

^bAnnealing was conducted at 200 °C for 5 min.
