Assuming your using version higher than 2016b of MATLAB:
Str='A':'F';
Z=repmat(Str,strlength(Str)-1,1);
f = @(x)regexp(""+x,'\w*','match');
ZZ=[f(tril(Z)),f(triu(Z,1))];
S=cell2struct(ZZ,{'First_Part','Second_Part'},2)
For older versions:
Str='ABCDEF';
Z=repmat(Str,strlength(Str)-1,1);
f = @(x)regexp(cellstr(x),'\w*','match');
ZZ=[f(tril(Z)),f(triu(Z,1))];
S=cell2struct(reshape(ZZ,[],2),{'First_Part','Second_Part'},2)
